I did not check other one projects yet. Could there have been a mistake when restarting or are these lost? I imported all lost versions... can you check?

Another thing would be to just restart SqueakSource once per week. It sounds like a hack, but calling it "rejuvenation" makes it sound better :-) I suggested both in the past, but there was a reason why both where not done. But I don't remember...

Re: [Pharo-project] [squeak-dev] Accessing external resources in a cross-platform way
by HernÃ¡n Morales Durand Feb. 3, 2011

Feb. 3, 2011

I've just implemented an initial release on top of FileSystem and ProcessWrapper (it uses some bit of Grease too). This is how it works in Windows: ( FSLocator sysEnvBinaries / 'notepad.exe' ) resolve " C:\WINDOWS\system32\notepad.exe " ( FSLocator sysEnvBinaries / 'X264VFW.DLL' ) resolve " C:\WINDOWS\system32\X264VFW.DLL " ( FSLocator userBinaries / 'excel.exe' ) resolve " C:\Archivos de programa\Microsoft Office\OFFICE11\EXCEL.EXE " ( FSLocator userBinaries / 'firefox.exe' ) resolve " C:\Archivos de programa\Mozilla Firefox\firefox.exe" So #sysEnvBinaries search in the OS PATH environment variable locations (which is usually pretty fast) and #userBinaries in the "program files" locations (it could be slow depending the amount of entries). It's only tested under Windows, IIRC user binaries in Unix are inside "/usr/local/bin" but you may tweak it to other locations, I have no access to a Unix or MacOS. Feel free to suggest or add any enhacements you like.

Read-Only Execution for Dynamic Languages. Abstract Supporting read-only and side effect free execution has been the focus of a large body of work in the area of statically typed programming languages. Read-onlyness in dynamically typed languages is difficult to achieve because of the absence of a type checking phase and the support of an open-world assumption in which code can be constantly added and modified. To address this issue, we propose Dynamic Read-Only references (DRO) that provide a view on an object where this object and its object graph are protected from modification. The read- only view dynamically propagates to aggregated objects, without changing the object graph itself; it acts as a read-only view of complex data structures, without making them read-only globally. We implement dynamic read-only references by using smart object proxies that lazily propagate the read-only view, following the object graph and driven by control flow and applied them to realize side-effect free assertions.

Hmm... normally these warnings should be suppressed when loading code automatically in non-interactive mode (that is, monticello loads code vs. accepting in the browser). In the browser, we want lots of warnings. When we compile code, we just want Transcript notifications. Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.
